Abstract
Description
- The present invention relates to an IC card and, more particularly, to an IC card having a shutter.
- Fig. 1 is a perspective view showing a conventional IC card 1 having a
shutter 3 with theshutter 3 closed. The IC card 1 is constructed of a circuit board (see FIGS. 3 and 4) on which are mounted a plurality of electronic parts. The board is mounted in aframe 2, and panels 4 (generally metallic panels) are attached on the front and back sides of theframe 2 respectively to protect the electronic parts. Theshutter 3 which is generally formed of a metallic material is arranged on the front of the card body so as to selectively open and close the IC card 1. FIG. 2 is a perspective view showing the conventional IC card, connected to an external device, having theshutter 3 with theshutter 3 opened. Under this condition, a plurality ofelectrode terminals 6 arranged on anelectrode terminal board 5 are exposed to the outside to be electrically connected to an external device. Theelectrode terminal board 5 is mounted on the circuit board. Theshutter 3 opens and closes as follows: when the IC card 1 is inserted into the external device, theshutter 3 opens by virtue of the fact that apin 100, disposed on a connector (not shown) of the external device, pushes theshutter 3 alongshutter grooves 7 formed on the sides of theshutter 3 in a direction opposite to that of the insertion direction of the card 1. Theshutter grooves 7 includerespective opening 70 formed on a front sides of theframe 2 where the IC card 1 is inserted and thegrooves 7 extend along both sides of theelectrode terminal board 5 from theopenings 70. Further, when the IC card 1 is pulled away from the external device, theshutter 3 closes due to the restorative tension force ofsprings 3a (see FIG.5). One end of thespring 3a is fixed byscrews 3b to the frame or the board, while the other end of thespring 3a is fixed to theshutter 3. - FIG. 3 is a cross-sectional view illustrating a shutter portion, taken along line III - III of FIG. 1, with the
shutter 3 closed. FIG. 4 is a cross-sectional view illustrating the shutter portion, taken on line IV - IV of FIG. 2, with theshutter 3 open. As described above, thecircuit board 8 is fixed in theframe 2, thecircuit board 8 includes obverse and reverse main planes on which theelectronic parts 9 are mounted respectively. Theelectrode terminal board 5, having a plurality ofelectrode terminals 6 for electrically connecting the electronic parts to the external device, is arranged on one end of the obverse main plane of thecircuit board 8. Theseelectrode terminals 6 are electrically connected to theelectronic parts 9. - FIG. 5 is a perspective view showing the entire
conventional shutter 3 shown in FIGS. 1 to 4. FIG. 6 is a cross-sectional view showing the shutter portion perpendicular to the sliding direction of theshutter 3, taken along line VI - VI of FIG. 1. As shown in FIG. 5, theshutter 3 comprises ashutter body 3c,shutter bends 3d which are formed by bending the right and left ends of theshutter body 3c with respect to a sliding direction of theshutter body 3c and backward extendingportions 3e respectively extending backward on the right and left sides ofshutter body 3c. Theshutter 3 further comprisesspacer portions 3f which are formed by bending parts of the extendingportions 3e in the same direction as theabove shutter bends 3d andspring fixing portions 3g. As shown in FIG.6, theshutter bends 3d are mated with theshutter grooves 7 and travel in thegrooves 7. The backward extendingportions 3e are provided to prevent theshutter 3 from leaning rightward and leftward during the opening and closing operations of theshutter 3. Thespacer portions 3f are provided for a fixed space between theshutter body 3c and theelectrode terminals 6 so that theshutter 3 andelectrode terminals 6 do not contact each other. Moreover, one end of thespring 3a is fixed to thespring fixing portion 3g and the other end of thespring 3a is fixed by thescrew 3b to the frame or the board. Other grooves (not shown), where thespring fixing portions 3g are fitted, may be disposed on the sides of the frame or the board. The spring fixingportions 3g may travel along the above grooves. - In such a conventional IC card having a shutter as described above, in order that the shutter be arranged to open and close over the electrode board without the shutter being lifted up, the distance denoted by character A in FIG. 3, where the panel disposed on the upper surface of the frame overlaps with the electrode terminal board, should be long. Because of the entire IC card structure, however, the distance A cannot be long. Accordingly, the shutter can be lifted up. Furthermore, if a force is added in the direction indicated by the character B in FIG. 3, the shutter may lift up causing the shutter to be deformed.
- The present invention overcomes the above-described problems and provides a highly reliable IC card whose shutter is prevented from being lifted up.
- The present invention provides an IC card having a shutter for being connected to an external device comprising: an IC card body containing at least one electronic part therein, electrical connecting means arranged on the IC card for electrically connecting the electronic part to the external device, the electrical connecting means being capable of being exposed to the outside of the IC card body, a shutter including bends for covering the electrically connecting means for protection, the bends being arranged so as to embrace at least one part of the IC card body and the electrical connecting means on the right and left ends of the shutter with respect to the open-and-close direction of the shutter; and L-shaped grooves, whose vertical cross section with respect to the open-and-close direction of the shutter is L shaped, for receiving the bends of the shutter, the groove extending from an insertion side and of the IC card body, through both sides of the electrical connecting means to the open direction of the shutter.
- The shutter with the IC card according to the present invention slides while the bends on both sides of the shutter embrace both ends of the electrode terminal substrates or one portion of the IC card body, so that the shutter is not easily lifted up nor does it get deformed after being lifted up even if a force is applied to the shutter in directions other than the sliding direction.
-
- FIG. 1 is a perspective view showing the conventional IC card having the shutter closed;
- FIG. 2 is a perspective view showing the conventional IC card having the shutter with the shutter opened;
- FIG. 3 is a cross-sectional view illustrating a shutter portion, taken along line III - III of FIG. 1;
- FIG. 4 is a cross-sectional view illustrating the shutter portion, taken along line IV - IV of FIG. 2;
- FIG. 5 is a perspective view showing the entire conventional shutter;
- FIG. 6 is a cross-sectional view showing the shutter portion, taken along line VI - VI of FIG. 1;
- FIG. 7 is a perspective view illustrating an entire shutter to be arranged in an IC card according to an embodiment of the present invention;
- FIG. 8 is a cross-sectional view illustrating the shutter portion with the IC card, taken in the same position as in FIG. 6; and
- FIG. 9 is a perspective view depicting the entire shutter to be arranged in the IC card according to another embodiment of the present invention.
- An embodiment of the present invention will now be described with reference to the accompanying drawings. FIG. 7 is a perspective view illustrating the shutter to be arranged in the IC card according to an embodiment of the present invention. As shown in FIG. 7, L-
shaped bends 30d are formed along the total length in the open-and-close direction of ashutter body 3c. FIG. 8 is a cross-sectional view illustrating the shutter portion of the IC card, taken along a line perpendicular to the sliding direction of the shutter (in the same position as in FIG. 6). As shown in FIG. 8, in the case of an IC card according to the present invention, the width of thecircuit board 8 should be shorter than that of theelectrode terminal board 5 at least in the shutter portion. Although the same is true in the conventional IC card shown in FIG. 6, conventionally, this was not necessarily required. By this arrangement, L-shaped grooves 7a are formed on the right and left sides of theelectrode terminal board 5. The L-shaped bends 30d formed on both sides of theshutter 30 extend along the L-shaped grooves 7a. Theshutter 30 is attached to slide, i.e., to open and close freely, over theelectrode terminal board 5 so as to embrace respectively the ends of theelectrode terminal board 5. The shape ofopenings 70 formed on the entrances to thegrooves 7a, i.e. an insertion face of theframe 2, is the same as in the conventional type shown in FIG. 1. Other parts are the same as in the conventional IC card, the explanations therefor being omitted. - In such a
shutter 30 as constructed above, even if the distance indicated by character A in FIG. 3, where thepanel 4 overlaps theelectrode terminal board 5, is short, theshutter 30 does not lift up. Further, theshutter 30 is less liable to become deformed or the like even if a force is applied to it in directions other than the sliding direction thereof, because the L-shaped bends 30d of theshutter 30 are slidingly supported by the under-face of theelectrode terminal board 5. - Although in this embodiment the L-
shaped bends 30d are formed along the total length of the sides of theshutter body 3c, as shown in FIG. 9, L-shaped bends 31d of a shutter 31 may be formed by bending at least one part of both sides of theshutter body 3c, respectively. - Furthermore, the L-
shaped grooves 7a are formed by making the width of thecircuit board 8 shorter than that of theelectrode board 5. The present invention, however, is not limited to the above-mentioned arrangement. For example, grooves, whose vertical cross section is L-shaped, may be possible to formed differently in accordance with the bends of the shutter. - Moreover, the structures of the backward extending
portions 3e, springs 3a, etc. of theshutters 30, 31 are not limited to the above-described embodiments. - As has been described above, according to the present invention, since the right and left ends of the shutter, with respect to the sliding direction thereof, are bent so as to embrace the ends of the electrode terminal board, the shutter does not lift up, whereby a highly reliable IC card is provided.
- The invention has been described in detail with particular reference to the preferred embodiments thereof, but it will be understood that variations and modifications of the invention can be made within the spirit and scope of the invention.
